Metal Base PCB process capability
| Category | Capability | Details |
| PCB Material Brand | Goldenmax GL11, Guangzhou Aluminum | (Goldenmax GL11, Guangzhou Aluminum) |
| SolderMask | LB Brand | LB-1900W |
| Copper Thickness | 18um/25um/35um/70um（0.5oz/0.75oz/1oz/2oz） | Refers to the thickness of finished PCB outer copper，0.5oz=18um，1oz＝35um |
| PCB Thickness | 0.8-2.0mm | 0.8/1.0/1.2/1.6/2.0 mm |
| Thickness Tolerance( thickness≥1.0mm) | ± 10% | Thickness measurement position is the thickest position of the whole PCB (including copper + Soldermask + Silkscreen) |
| PCB Thickness Tolerance (Thickness <1.0mm) | ±0.1mm | Thickness measurement position is the thickest position of the whole PCB (including copper + Soldermask + Silkscreen) |
| Minimum Trace Width | ± 10% | At present,we can process min 8mil trace width,and ≥10mil is advised |
| Minimum Trace Distance | 8mil（0.2mm） | At present,we can process min 8mil trace distance,and ≥10mil is advised |
| Drilling Aperture | Hole size≥ PCB thickness ≥1.0mm | The minimum hole shall not be less than the thickness of the PCB, and it shall not be less than 1.0mm |
| Drilling Hole Tolerance | ±0.1mm | Hole tolerance is ±0.1mm, for example, designed for 1.5mm hole, the drilling hole of the final PCB in 1.4-1.6mm is normal. |
| Soldermask Type | Photosensitive ink | Photosensitive ink is now the most used type, thermosetting oil is generally used in low-grade light panels |
| Soldermask Bridge | 0.15mm | If the soldmask color is green or blue, the pad spacing must be bigger than or equal to 8mil; White and black ink pad spacing ≥10mil |
| Minimum Silkscreen Width | ≥0.15mm | Minimum width of characters is 0.15mm, if less than 0.15mm, the physical board may cause unclear characters due to design reasons. |
| Minimum Silkscreen Height | ≥1.0mm | Minimum height of characters is 0.8mm. If the height is less than 0.8mm, the characters may be unclear due to design reasons |
| Max Size | Standard：480x580mm | The limit size is the maximum size that can be machined, but the cost will increase due to plate waste and high processing costs |
| Max：580x1180mm | ||
| Dimension Accuracy | ±0.15mm | CNC contour tolerance is ±0.15mm, V-Cut contour tolerance is ±0.15mm, mold shaping contour tolerance is ±0.1mm |
| Panel: no gap between the panel | 0mm | The gap between the PCBs is 0mm |
| Panel: there are gaps between the panel | 2.0mm | If you want space between each PCB while panelling, the distance should be bigger than 2.0mm. |
